골전도(骨傳導)스피커{BONE CONDUCTIVE SPEAKER}Bone Conduction Speaker {BONE CONDUCTIVE SPEAKER}

본 고안은 인체의 두부(頭部)뼈에 진동자의 진동을 통하여 음성신호를 자각하여 인식할 수 있도록 하는 골전도(骨傳導)스피커에 관한 것이다.The present invention relates to a bone conduction speaker to recognize and recognize the voice signal through the vibration of the vibrator on the head bone of the human body.

좀더 구체적으로 상세히 설명하면, 직업성 및 노인성 난청의 청각장애인 이 사용하는 보청기나 주변의 이야기를 들으면서 통화가 요구되는 콜센터, 무전기 등에 사용되는 헤어밴드에 결합되는 구조의 골전도스피커는 진동판에 의하여 공기를 진동시켜 음파를 발생시켜 전달하는 것이 아니라, 진동자에 의한 음의 진동으로 변화시켜 물체에 직접적인 접촉에 의하여 전달하는 것으로 골도 즉, 인체의 머리부분의 뼈에 진동을 주며 이러한 진동을 청신경에서 감지하도록 하는 것인바, 고막의 진동에 의한 음성인식이 아니라 뼈의 진동에 의하여 음파가 인체의 청신경으로 전달이 되는 것이다.In more detail, the bone conduction speaker of the structure coupled to the headband used in the call center, walkie-talkie, etc., which requires a call while listening to the hearing aids and surroundings used by the hearing impaired people of occupational and elderly hearing loss is air by the diaphragm Rather than generating and transmitting sound waves by vibrating, instead of converting them into sound vibrations by vibrators and transmitting them by direct contact with objects, it vibrates bones, that is, bones in the head of the human body, and detects these vibrations in the auditory nerve. That is, the sound wave is transmitted to the auditory nerve of the human body by the vibration of the bones rather than speech recognition by the vibration of the eardrum.

이러한 목적의 골전도스피커는 일본국 특허 제2967777호로 이미 발명이 된바 있었으며, 선 발명은 도 7에 예시한 바와 같이 4방향의 연장면을 갖는 요크(1)에 중앙자극(2)과 보이스코일(3)을 설치하고, 서로 대향된 위치의 마그네트설치부(4)(4')에는 직방체의 자석(5)(5')을 설치하는 구조로 개선하여 스페이스의 활용과 중앙의 자극(2)의 지름을 크게 함과 보이스코일(3)의 회권수를 크게 할 수 있게 하여 음의 전달효과가 크고 외형의 크기를 작게 할 수 있는 골전도스피커를 제공하려는데 그 주된 목적이 있는 것이었다.The bone conduction speaker for this purpose has been invented by Japanese Patent No. 2,777,777, and the pre-invention includes a central magnetic pole 2 and a voice coil (2) in the yoke (1) having an extended surface in four directions as illustrated in FIG. 3) and the magnets 5 and 5 'of the rectangular parallelepiped are installed in the magnet mounting portions 4 and 4' at positions opposite to each other. The main purpose of the present invention was to provide a bone conduction speaker capable of increasing the diameter and increasing the number of turns of the voice coil (3), thereby increasing the sound transmission effect and reducing the size of the appearance.

그러나 이러한 선 발명의 구조에서는 직방체의 자석을 양측에서 서로 대향되게 2개로 설치하여야 하는 제조공정상의 불편성이 있어 생산성을 약화시키는 요인이 되었고, 2개의 자석이 설치되는데 따른 제조원가 상승의 비경제성이 있을 뿐만 아니라 제품의 조립 시 자석을 서로 대향된 위치에 설치하는 관계로 자석의 방향성을 정확히 맞추어야 그 특성이 저하되지 않는 관계로 이를 정확한 위치에 고정시켜야 하는 관계로 생산의 능률화를 가질 수 없는 제반의 문제점을 내재하고 있었다. However, in the structure of the above invention, the manufacturing process has to be inconvenient to install two magnets of the rectangular parallelepiped on both sides, which is a factor to weaken the productivity, and there is an uneconomical increase in manufacturing cost due to the installation of two magnets. In addition, as the magnets are installed at opposite positions when assembling the product, the orientation of the magnets must be precisely adjusted so that the characteristics of the magnets are not degraded. Was inherent.

본 고안은 이러한 문제점에 착안한 것으로 골전도스피커를 구성함에 있어 자석을 음성코일에 근접되게 설치하지 않고, 철편의 상부에 1개의 자석을 설치하는 구조로 하여 자석의 방향성을 맞추어야 하는 번거러움이 없으며, 음성코일의 크기를 확대시킬 수 있어 특성의 조정 폭을 크게 할 수 있음은 물론 자석의 크기 변화에 따른 강도 조절이 매우 용이하게 하고 크기를 소형화와 경량화를 가질 수 있는 골전도스피커를 제공하려는데 그 주된 목적이 있는 것이다.The present invention has been devised to solve such a problem, and in constructing a bone conduction speaker, the magnet is not installed close to the voice coil, and the structure of installing one magnet on the upper part of the iron piece has no hassle to adjust the direction of the magnet. The size of the voice coil can be enlarged to increase the adjustment range of the characteristics, and to provide a bone conduction speaker that can easily adjust the strength according to the change in the size of the magnet and have a small size and a light weight. There is a purpose.

이하 본 고안을 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 고안의 분리사시도를 도시한 것이고, 도 2는 본 고안의 종단면도를 도시한 것이다.1 is an exploded perspective view of the present invention, Figure 2 is a longitudinal sectional view of the present invention.

하우징(10)내에 수납 설치되는 요크(20)에 4방향으로 연장면(30)(30')을 구성함과, 이에 음성코일(40)과 중앙자극(50)을 형성하며 상부에는 철편(60)이 부착된 진동판(70)을 나사(80)로 고정한 것에 있어서,Extension surfaces 30 and 30 'are formed on the yoke 20 accommodated and installed in the housing 10 in four directions, thereby forming the voice coil 40 and the central magnetic pole 50, and the iron piece 60 on the upper portion. In fixing the diaphragm 70 with) to the screw 80,

본 고안은 철편(60)의 중앙부위에 영구자석(90)을 부착하여 된 것이다.The present invention is to attach a permanent magnet 90 to the central portion of the iron piece (60).

그리고 본 고안은 필요한 사정에 따라 요크(20)의 양단을 상향절곡부(100)를 갖도록 하여 안정감을 가질 수 있게 할 수도 있다.And the present invention may have a sense of stability by having both ends of the yoke (20) up bending portion 100, depending on the circumstances required.

상기한 영구자석(90)의 형상은 원형 내지 사각형 등의 다양한 형상체로 할 수 있다.The shape of the permanent magnet 90 may be a variety of shapes, such as circular to square.

또한 본 고안의 다른 실시예로는 요크(20)에 설치되는 음성코일(40)을 2 내지는 3개의 구성으로 하여 중앙자극(50)을 다수개로 형성할 수 있다.In addition, in another embodiment of the present invention, the voice coils 40 installed in the yoke 20 may be formed in two or three configurations, and a plurality of central magnetic poles 50 may be formed.

이와 같은 본 고안은 음성코일(40)에서 음성신호에 의한 음성전류가 발생하고 또한 중앙자극(50)에 N극과 S극의 자력이 발생하면서 영구자석(90)의 의하여 극성의 변화에 따른 흡인력과 반발력이 서로 교호로 작용하면서 진동판(70)을 진동시키게 되고 이러한 진동이 피부를 통해 머리뼈에 전달되고, 이러한 진동파장은 인체의 청신경을 자극시켜 음성신호를 감지할 수 있게 되는 것이다.The present invention has a suction force according to the change of polarity by the permanent magnet 90 while the voice current generated by the voice signal in the voice coil 40 and the magnetic force of the N pole and the S pole in the central pole 50. And the repulsive force acts alternately with each other to vibrate the diaphragm 70 and the vibration is transmitted to the head bone through the skin, this vibration wavelength is to be able to sense the voice signal by stimulating the auditory nerve of the human body.

그리고 본 고안은 사용과정에서 안정감을 주기 위하여 요크(20)의 양단을 상향 절곡부(100)로 구성하여 사용할 수 있다.And the present invention can be used to configure both ends of the yoke 20 to the upper bent portion 100 in order to give a sense of stability in use.

본 고안은 진동판(70)의 상부의 위치에 영구자석(90)이 설치되기 때문에 자석의 형상과는 무관하게 사용할 수 있는 것이고 자석의 크기가 변경되더라도 무관하게 조립할 수 있는 것이다.The present invention can be used regardless of the shape of the magnet because the permanent magnet 90 is installed in the upper position of the diaphragm 70 and can be assembled regardless of the size of the magnet.

이상에서와 같이 본 고안은 골전도스피커를 제조함에 있어 영구자석이 1개의 단위부품으로 소요되고 자석의 방향성을 정확하게 할 필요성이 없고, 그 조립공정 역시 매우 간단하기 때문에 제조원가의 절감을 기할 수 있는 경제성이 있으며, 자석이 음성코일의 외주면부분에 있지 않고 철편의 상부에 위치하므로 유효공간을 극대화 할 수 있어 음성코일의 크기를 확대시킬 수 있는데 따라 특성의 조정이 매우 크며 자석 역시 그 크기의 조절이 가능하고 전체적인 크기의 소형화, 경량화를 가질 수 있는 매우 유용한 고안이다. As described above, the present invention requires a permanent magnet as one unit part in manufacturing a bone conduction speaker, and there is no need to precisely orient the magnet, and the assembling process is very simple. Since the magnet is not located on the outer circumferential surface of the voice coil, it is located on the upper part of the iron piece, so the effective space can be maximized, and the size of the voice coil can be enlarged. It is a very useful design that can have the overall size miniaturization and light weight.
